Answer:
11
Step-by-step explanation:
if the lines are parallel then
4x = 2x + 22
2x = 22
x = 11
Answer:
0=6
Step-by-step explanation:
(You will have to rearrange terms.)
7x-3=3+7x
7x-3=7x+3
(now add three to both sides.)
7x-3=7x+3
7x-3 <u>+3</u>=7x+3 <u>+3</u>
7x=7x+6
<u></u>
<u>(</u>Now subtract 7x from both sides of the equation.<u>)</u>
7x=7x+6
7x-7x=7x+6-7x
0=6
and that's how you get your answer.
I hope this helps you. :)
Divide until you get one moth alone then multiply then simplify if you don't know how to simplify please pm me.
Well, to find out whether she spent more time getting dressed or eating breakfast, we simply have to compare the fractions of the hour that she took on each.
We know that she took 3/6 of an hour to get dressed and 1/4 of an hour to eat breakfast. To find out which activity she spent more time on, we simply need to see which fraction is bigger.
To do this, we must first reduce the fractions to lowest terms. 1/4 is already in lowest terms, so we can leave that alone. 3/6 can be reduced, however, and since 3 goes into 6 twice, it reduces to 1/2.
Now, we can compare the fractions.
Is 1/2 of an hour or 1/4 of an hour more?
The answer is 1/2, so now we know that Bailey spent more time getting dressed than eating breakfast.
Hope that helped! =)
Options :
A. The initial number of bacteria is 7.
B. The initial of bacteria decreases at a rate of 93% each day.
C. The number of bacteria increases at a rate of 7% each day.
D. The number of bacteria at the end of one day is 360.
Answer:
C. The number of bacteria increases at a rate of 7% each day.
Step-by-step explanation:
Given the function :
f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :
The function above represents an exponential growth function :
With the general form ; Ab^x
Where A = initial amount ;
b = growth rate
x = time
For the function :
A = initial amount of bacteria = 360
b = growth rate = (1 + r) = 1.07
If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;
1 + r = 1.07
r = 1.07 - 1
r = 0.07
r as a percentage ;
0.07 * 100% = 7%
